ROVIO maize pickers: for high-performance harvesting.

ROVIO 4-series: We've listened to our customers and have completely rethought our maize picker. With its revised power train and a new picking gear unit, the new ROVIO maize picker achieves throughput up to 30% higher than its predecessor. The symmetrical linear picking rollers ensure that only the cob itself is picked and no residual parts of the plant are able to enter the combine harvester, regardless of the operating conditions. This makes harvest disruptions a thing of the past.

Completely revised to make life easier for you.

Top performance – with revised power train and up to 30% higher performance
Precision – excellent work quality, even at high speed
Field hygiene – market-leading solutions to combat the European corn borer

Revised design:

High performance you can count on.

The CLAAS ROVIO 4-series maize pickers are designed to match the full spectrum of customer requirements and offer many advantages, including a more powerful drive and a new picker gearbox. These allow the maize harvesting performance of the pickers to be increased by up to 30% compared with their predecessors.

Advantages:

Linear picking rollers with front bearing for constant throughput speed
Picker speed adjustment possible at high ground speeds
Four bolt-on knives per picking roller for easy replacement
Wear-resistant tungsten carbide coating to keep down cost of parts and total cost of ownership

Innovative hood design.

For gentle crop handling.The new, innovative design of the hood tips makes for gentler crop handling, even when operating under challenging conditions or when negotiating curves. The wear parts fitted in the hoods can be replaced easily if necessary and the height of the tips can be adjusted quickly without tools by means of a simple screw mechanism.

Hood folding mechanism:

Fast access to picking unit as hoods can be folded up without using tools
New, simplified folding mechanism reduces the width of the rigid pickers on the transport trailer during road travel
Easy and fast access to picking unit for all maintenance and cleaning tasks

Easy handling.

Practical maintenance position.The system for opening the hoods provides quick and easy access for maintenance or cleaning. Only a few simple steps are required to put a hood into the maintenance position without tools.

The conveyor chains can therefore also be tensioned and changed quickly, easily and conveniently. Once a hood has been moved to the maintenance position, a simple assembly lever is all that is required to release, tension or replace a chain.

Flat working angle.

Minimal cob losses.At 17°, the ROVIO maize pickers have the flattest operating angle in the market.

This design has two major advantages:

Reduced cob losses, especially those resulting from "knocked cobs"
In laid maize in particular, the flat angle and the hood shape help make for blockage-free operation

The best of all worlds:

Precision with power.

With the new ROVIO maize picker, you benefit from the best of all worlds. Its revised horizontal choppers integrated in each picking unit ensure precise and even chopping. You don't have to accept any trade-offs when working: you get inch-perfect results, yet can still work at high speed with high output.

Advantages:

Improved quality of chopped material thanks to innovative position of horizontal choppers
Knives sharpened on 3 sides for precise chopping and low power requirement
Tungsten carbide coating to protect against wear
Knives can be changed quickly and easily

Precise adjustment to ground contours.

You can count on a uniform stubble height.

AUTO CONTOUR enables precise, automatic transverse and longitudinal adaptation of the front attachment to the ground contours detected by a sensing bracket. Two hydraulic rams on the feeder housing perform lateral levelling on the basis of the information from the sensors. The required cutting height can then be set easily via CEBIS.

Advantages:

Compensates for all ground undulations parallel and transverse to the direction of travel
Consistent stubble height facilitates subsequent tillage
AUTO CONTOUR reduces the operator's workload

Automatic steering.

Noticeable workload reduction.

The ROVIO maize pickers are available with the AUTO PILOT automatic steering system. The AUTO PILOT system scans two rows of plants simultaneously with its central sensors and translates this input into corresponding steering movements. The system identifies and compensates for gaps in the crops and operates optimally with row widths of up to 80 cm.

Advantages:

Noticeable reduction in operator's workload through automatic steering
Reliable guidance along rows, even in crops with gaps
Improved tolerance for variations in row spacing

The sunflower kit.

Flexible operation.Simply turning the feeder chain round is all that is required to switch over quickly for sunflower harvesting. In addition, rigid knives are fitted on the picking plates along with side hood extensions and a raised rear wall panel.
